Summary
The Hochiki CHQ-POM is an intelligent powered output module built to supply third-party devices from the ESP loop, with a user-selectable output from 2 to 32 mA in 2 mA steps so you can match the exact current draw of the equipment you’re connecting rather than over or undersizing the circuit.

That selectable range means you’re not carrying multiple fixed-output modules for different third-party kit – one CHQ-POM covers a spread of current requirements, cutting the number of part numbers you need to stock for a job. It also includes two monitored inputs, giving it a wider role on site than Hochiki’s sounder and base products in the ESP range, which are built purely for audible output rather than input monitoring.
On site, the module’s small footprint lets you fit it alongside devices such as the IFD-E, and its colour-coded flying leads make the termination straightforward during first fix. Just remember it needs to sit next to the Type 1 detection device it’s serving, with no transmission path in between.
Features
- Selectable current output – set 2-32mA in 2mA increments to match the third-party device’s actual power draw
- Two monitored inputs – watch extra circuits without fitting a separate monitoring module
- Compact enclosure – small enough to mount alongside third-party devices like the IFD-E
- Colour-coded flying leads – makes termination quicker and reduces wiring mistakes on site
- Digital ESP communication – integrates into the loop alongside other ESP devices
FAQ
It’s a powered output module that supplies 24V DC to third-party equipment connected to an ESP loop, such as the IFD-E, while also giving you two monitored inputs on the same small unit. It’s not a detector or sounder itself – it’s an interface device. The module must be installed next to the Type 1 detection device it’s serving, with no transmission path between them. Plan your containment and cable runs with this in mind before first fix. The output is user-selectable across 2 to 32mA in 2mA steps, letting you set it to suit the connected device’s current requirement. The datasheet doesn’t detail the exact selection mechanism, so check the installation manual on site if you’re unsure. Yes, the two inputs are designed to be monitored and come with EOL resistors for normal state and input activation states, so they can supervise external circuits in the usual way. Check the input ratings in the specification table against the circuit you’re monitoring before wiring in. The module draws a typical quiescent current of 200 μA at 41V, which you should factor into your loop power budget alongside its alarm current of 2.3 to 32.3mA when the output is active. The datasheet doesn’t specify a cable gauge for the flying leads, so confirm compatible cable sizes with the installation documentation or Hochiki technical support before ordering terminals.What is the CHQ-POM actually for?
